Building a Strong Maths Foundation


Year 4 is all about solidifying basic mathematical operations.

Addition and subtraction

Adding and subtracting whole numbers (including multi-digit numbers) fluently.

Multiplication and division

Mastering multiplication tables up to 12×12 and understanding division as the inverse of multiplication. They should be able to solve problems involving multiplication and division with whole numbers.


Year 4 dives deeper into fractions, focusing on recognising and comparing fractions with different denominators. Adding and subtracting fractions with the same denominator.


Year 4 students will develop their problem-solving skills by:

Estimating and rounding numbers to a suitable degree of accuracy

Using appropriate mathematical vocabulary (e.g., sum, difference, product, quotient)

Expanding Mathematical Horizons


Year 4 students will explore measurement in more depth, learning to:

  • Convert between different units of measurement (e.g., meters to centimetres, grams to kilograms)
  • Measure and calculate the perimeter and area of rectangles (including squares)
  • Measure and record time (including using a 12-hour clock and reading analog clocks)


Year 4 introduces basic geometric concepts, including:

  • Identifying and classifying 2D shapes (e.g., triangles, squares, pentagons)
  • Recognising angles and classifying them as right, acute, or obtuse
  • Understanding lines of symmetry in 2D shapes

Data Handling

Year 4 students will be introduced to basic data handling skills, learning to:

  • Collect, organise, and represent data using pictograms, bar charts, and tally charts
  • Interpret and analyse simple data sets

Developing Mathematical Confidence

By the end of Year 4, students should be comfortable applying these mathematical skills to solve problems in real-world contexts.


Year 4 students should be able to explain their thinking and justify their answers mathematically.


They should be able to approach problems strategically, break them down into smaller steps, and persevere until they find a solution.

Remember, this is a guideline! Some Year 4 students may be ahead of this benchmark, while others may need more time to solidify these concepts. The most important thing is to encourage a love of learning and a positive attitude towards maths.
